config: trats: trats2: extend dfu_alt_info by env update settings This change allows updating environment stored on MMC by dfu or thor. New setting: - "params.bin mmc 0x38 0x8" File params.bin can be generated by: tools/mkenvimage. e.g. ./mkenvimage -s 4096 -o params.bin <env_text_file> Every new env variable in text file should start with a new line. Sample env text file: - board/samsung/common/dfu_sample_env.txt Requirements: - file name: "params.bin" - file size: 4096 Bytes - the same as CONFIG_ENV_SIZE. Other size will cause CRC miscalculation at boot.
